Be it. known thatI, NATHAN F. WESTON, of Boston, in the county ofSnfi'olk, and State of Massachusetts, have invented: a Device forUniting-or Joining the ends of Lead Pipe; and do hereby declare thefollowing to be a full, clear, and exact ldescriptionythereof, duereference being had to the accompanying drawings, making part of thisspecification, and in which- Figure 1: is a side elevation.

Figure 2, a longitudinal section; and

Figure 3, a transverse section of my invention. v

Figure 4 is a side elevation of the expanding-plug, to behereinafterdescribed.

Fignre5, being an elevation of one of the tapering-sleeves, constitutingpart of the invention.

In the practical operation of plumbing it often becomes necessary tounite the ends of two portions of a lead pipe. This has formerly beendone by the use of solder, a large mass of which is applied around thejoint, reqniring much time and an experienced person to accomplish itproperly. 7

' The object of my invention is to unite the ends of 'the pipe withoutthe aid of solder, and in av very easy and expeditious manner, and byany person of ordinary intelligence. 7

The invention consists in a. peculiarly formed coupling o'rconnection-joint, which draws the two ends of the pipe firmly andtightly together. v v

In the drawings illustrating my invention, the two ends of the lead pipeare shown at a a. The inner part of the coupling is composed of ahollow, cylindrical expanding-plug, A, in'form composed of two conicfrusta, united at their larger bases in a ring or lip, b, circumscribingthe middle of the circumference of the plug so formed. Two cylindricaltapering-sleeves c c, for receiving the ends of the pipe, which areinserted within them through'their smaller apertures, thesesleeves'having screw-threads cl d out upon a portion of their outerperipheries, one being a right and the other aleft-handed screw.. A nut,e, having female screws ff corresponding to the male screws 01 d, is tobe screwednpon the sleeves c a.

The operation of applying the above-described device is as follows: Thesleeves c c are to be passed over the ends of the pipe, small end first,to about their whole length, and the end of the pipe subsequently spreadout to fill, or partially fill, thein'terior of the sleeves, the nut eat this time being partially screwed upon one of them. One endof theexpanding hollow-plug A is then to be inserted in either of the sleeves,or the ends of .the pipe enclosed by them, and the nut .e screwed uponboth' of them. The plug'A, during the operation of screwing up the nute, performs a twofold purpose: 'it expands the lead pipe tightly withinthe sleeves, and at the same time forces the two ends of the pipe upagainst the ringv b, or against washers or psckings placed on each sideof it.

The above-described device forms a very strong and perfectly tightjoint. It-can be applied very expe ditiously, and by person-not at allconversant with the business of plumbing. In addition to this, theactual expenseof applying it is considerably less than by the solderingprocess.

I claim the device for uniting the ends of lead pipe and dispensing withthe use of solder, consisting of the hollow elrpanding-plug A, sleeves cc,'and nut) 0, combined and operating together, substantially as beforedescribed.
